Abstract (en)
[origin: WO2018210607A1] The invention relates to a machine for the precision machining of toothed workpieces, which machine comprises a tool spindle (30) for mounting a precision machining tool (31). The tool spindle can be driven to rotate about a tool spindle axis (B) by means of a tool spindle drive (32). A control device (70) takes at least one measurement of the distance from the precision machining tool (31) by means of a distance sensor (60) and, on the basis of said measurement(s), determines at least one characteristic variable of the precision machining tool, in particular the outer diameter thereof. The distance sensor can operate optically in particular.
